Patented Aug. 25. 1931 UNITED STATES PATENT OFFICE 101m HINES, OF ASTORIA, NEW YORK, ASSIGNOR T SEGAL LocK & HARDWARE co. INC., on NEW YORK, N. Y., A, CORPORATION or NEW YORK LooK . Application filed Ma 1a, 1929. Serial No. 364 247.

This invention relates to a lock andaims to provide a device of this character embodying functionally and structurally improved characteristics.

It is an object of the invention to provide an improved lock which may with facility be applied to a right or left hand closurev and the latch of which may be operated by means of a latch lever or knob spindle.

A further object of the invention is that of constructing a device of this type in which the mechanism will be so arranged that there will be no likelihood of jamming even if the bolt be left partially projected and thereupon an attempt is made to operate the lock bythe key mechanism.

A still further object. is that of furnishing a lock, the parts of which will be relatively few in number and individually simple and rug ed in construction, these parts being capab e of assemblage by relatively plate removed to disclose the enclosed mech-' anism;

Figs. 2, 3.and 4 are perspectlve views of "various units in the mechanism;

Figs. 5 and 7 are side views thereof;

Fig. 6 is a view taken along the line 66 of Fig. 5 and Fig. 8 is a side view of the lever shown in Fig. 7. i

In these views, the numeral 10 indicates a lock casing provided with a facing plate 11 formed with openings through which a bolt 12 and latch-head 13 are projectable, andalso having openings by means of which pins 14: are rendered accessible; The lock casing may havean opening accommodating the end of a cylinder 15 to' the plug of which an operating. lever 16 is secured. Ob-

-"viously, however, any other suitable form lever, 22 has a projecting arm 24 which rides of key mechanism might be employed. The case plate (not shown) may likewise be formed with an opening carrying an operating lever corresponding to the lever 16 and actuated by a thumb piece projecting from 55 the inner face of the door.

The bolt 12 has an extension 17 formed with a slot 118 within which a'lug 19 rides. which lug projects from the casing. Thus,

the bolt and its extension are guided in their Gq movements by the lug and contact with the edges of the opening in the facing plate. A lever 20 is pivotally carried by the extension 17 as by a pin 21 and the rear end of this lever may terminate in a hook-shaped projection 22 forfcooperation with a'lug 23 forming a part of the casing, this cooperation occurring when the bolt is wholly retracted asthas been shown in Fig. 1. The

in the space extant between a pair of lugs- 25 forming apart of the extension 17 and this position of the parts is maintained normally by means'of a spring 26 cooperating with the lever.

The latoh-head 13 is carried at the outer end of a rod 27 suitably guided by projections extending from the casing and a spring 28 serves normally to maintain the latch head projected. Adjacent the rear end of the rod 27 is a plate havingoflset end portions 29 and one of these is engaged by the upper end of one of a pair of levers 30 pivotally mounted by the casing as at 31 and acted upon by springs 32. It will be understood that in lieu of a pair of plates as shown in Figs. 1 and 8, that a single plate structure might be utilized. In any event, it is to be noted thatv the lock casing is formed with openings in line with collar por- 9-13 tions 33 which-have irregular bores, to receive a spindle 34. This spindle in accordance with conventional construction may be split, i. e. include two relatively rotatable sections connected to each other and each receiving at their outer ends a suitable knob or handle. These collars form parts of ac tuating elements which additionally include plate portions 35 having recesses 36. Ob-

viously, a' rotation ofthespindle carrying the case.

with it one of the collar portions will result in a swinging of the lever or levers resulting in a retraction of the latch head.

Disposed below these actuating elements are a pair of levers which as shown in Figs. 1 and 4 include bodies 37 pivoted as at 38 and having upwardly extending portions 39 and downwardly extending ofi'set end portions 40, it being noted that between these end portions, shoulders 41 are provided.

The offset end portions are adapted to be engaged by the ends of latch levers 42, each ordinarily terminating in thumb portions although this need not necessaril be It is in any event apparent that if the members 42 are rocked upwardly, they will carry with them the outer ends of thelevers 37 which due to the fact that their shoulders 41 engage with the lever or levers 30 will rock the latter to again effect a retraction of the latch-head.

The pins 14 are pivotally connected by a yoke or lever 43 which. may be mounted upon the pin 38 and one of these pins is extended to have a body 44 which may present recesses 45 in its upper edge for cooperation with a spring 46. This body mounts by means of a pin and slot construction 47 a lug 48 having an offset end portion 49 which is of a width such that it may be accommodated readily within the recess 38 of one of the plate portions, it being moreover apparent that the end portion 49 may extend beyond the side face of the plate 35 with which it is cooperating and into the path of' travel of the upper extension 39 of the lever 37.

hen in the position shown in Fig. 1, the latch may be retracted by operating either one of the knobs or the latch levers 42.

However, if the upper pin-14 is projected inwardly, an actuation of the lock may only be caused by the inner knob and latch lever or the knob or latch lever acting independ ent of each other.

If it is desired to retract the latch-head by means of the key mechanism, this may be achieved readily in that a plate 50 is rockingly secured to the extension 17 and when the bolt is retracted projects in the path of travel of the lever 16, the position of this bolt and its arm being maintained by a spring 51. A lever 52 may be pivotally mounted by the pin 21 and have its upper end cooperating with the projection which forms a part of the bolt 50 and the lower end of this lever may ride within the space extant between the latch-head 13 and a shoulder 53 formed to the rear of the same. Obviously, an actuation of the key mechanism will initially result in a retraction of the bolt 12.

A continued rotation of the lever 16 will cause the same to strike against the extension of the plate 50, thus rotating the latter and swinging the lever 52 to retract the latch-head. Due to this arrangement of the parts, it will likewise be understood that if a person on the inside of the closure has left the bolt partially projected which would ordinarily result in the lever 16 amming against the lug 25 or riding into the space between the extension of the bolt and this lug, no dii'liculty will be experienced. More particularly, it will simply be necessary to reverse the rotation of the lever and the latter will clear the extension of the plate due to the fact that this plate will simply swing upwardly and after the lever has shifted past the same will snap back into position. Thereupon, the bolt 12 may be wholly projected and now upon the direction of movement of the lever being reversed, the bolt 12 will be completely retracted and the latch 13 will move in a similar manner.

The lock as illustrated be applied to a left hand door. If it is to be applied to a right hand door, this may be achieved by simply withdrawing the latclrhead to a position within the-casing and reversing the same. Thereupon, that offset end portion of the plate 29 which has heretofore cooperated with one of the levers 30 will cooperate with the other of the same. Additionally, the block 48 will be removed and reversed so that its offset end portion 49 will extend in, a direction opposite from that shown in Fig. 8, in other words the end portion 49 will be offset to the left rather than to the right as it now appears. Thus, the outermost of the knob and/or latch lever actuated elements may be locked by an inner projection of the uppermost pin.

From the foregoing, it will be appreciated that among others the objects specifically aforementioned. are achieved. It will, moreover, be appreciated that numerous changes in construction and rearrangement of the parts might be resorted to without departing from the spirit of the invention as defined by the claims.

Having described my invention, what I claim new and desire to secure by Letters Patent, is:

1. A lock including, in combination, a latch, a pair of latch members, a pair of pivotally mounted levers each to be swung y one of said latch members for operating said latch, means connecting said latch to said levers, a spindle, a rotatable plate to be connected to said spindle, said plate bearing against said means whereby when the plate is rotated, said means will again be operated to retract said latch, said plate being formed with a rccessdisposcd adjacent one of said levers, and means projectable into the recess of saidplate and path of travel of such lever to prevent operative movement of either.

2. A look including, in combination, a latch, means for operating said latch, a

block, an end member associated with said block said block beingoapable of projection into the path of travel of said operating means whereby the operating means is rendered immovable, and said end member being movable so that its position with respect to the block may be reversed. a

3. A look, including, in combination, a bolt, means for projecting and retracting 10 said bolt, means associated with said bolt for locking the same in projected or retracted position, and spring pivoted means whereby said locking means are rendered inoperative.

In testimony whereof I. aflix my signature.
